- Abstract
Purpose: To examine the effect of trabeculectomy on ocular and corneal higher order wavefront aberrations. Methods: Trabeculectomy with a limbal-based conjunctival flap was performed in 13 patients (13 eyes). Ocular and corneal higher order aberrations were measured using a wavefront analyzer before and after surgery. The higher order aberrations for a 4-mm pupil diameter were expanded into Zernike's polynomials. Coma aberration, spherical aberration, and total higher order aberrations were evaluated as root mean square values. Results: Mean intraocular pressure was significantly reduced from 15.5 ± 3.1 mmHg preoperatively to 7.5 ± 3.5 and 7.2 ± 4.4 mmHg at 1 and 3 months after surgery, respectively. The mean spherical equivalent refractive error was not changed by the surgery. Mean vector powers for surgically induced refractive changes at 1 and 3 months postoperatively were 1.29 ± 0.69 and 1.30 ± 0.89 diopters, respectively. Corneal coma-like, spherical-like, and total higher order aberrations were not significantly changed by surgery. Trabeculectomy significantly increased ocular coma-like ( P = 0.0021) and total ( P = 0.0019) higher-order aberrations at 1 month, but not at 3 months postoperatively. Conclusion: Ocular coma-like and total aberrations were significantly increased at 1 month after trabeculectomy with a limbal-based conjunctival flap, but they had returned to normal levels by 3 months.
